What do you think the world would look like after 70 years?

im just enjoying judy garland's somewhere over the rainbow which has been made 70 years ago,..it came into my mind, that the song as just as good as it is, even to the least it was made 70 years ago,. the people back then would have been very creative and somehow still living in a simple backwoods life, so unlike today were i can only hear some bad "hook-me-up in bed" rap music and some annoying justin beiber high-pitched girly singing
